Study Notes
Vertebral Column Overview
- The vertebral column consists of different segments: cervical, thoracic, lumbar, sacrum, and coccyx.
- Cervical vertebrae are the topmost vertebrae, typically consisting of seven vertebrae (C1-C7).
- Thoracic vertebrae are located in the mid-back, usually numbering twelve (T1-T12).
- Lumbar vertebrae comprise the lower back and consist of five vertebrae (L1-L5).
- The sacrum is a triangular bone made up of five fused vertebrae, forming the back of the pelvis.
- The coccyx, or tailbone, forms the terminal end of the vertebral column and is composed of three to five fused vertebrae.
Key Vertebral Components
- Transverse Process: Projections on either side of a vertebra that provide attachment for muscles and ligaments.
- Spinous Process: The bony projection off the back of a vertebra, serving as an attachment point for muscles.
- Intervertebral Foramen: Openings between vertebrae that allow spinal nerves to exit the spinal column.
- Intervertebral Disc: Fibrocartilaginous cushions between vertebrae that act as shock absorbers.
- Pedicle: The bony part of a vertebra that connects the body to the vertebral arch.
Verterbral Structure
- Body of Vertebra: The anterior portion that bears weight.
- Vertebral Foramen: The central hole in each vertebra through which the spinal cord passes.
- Vertebral Arch: The arch formed by the pedicle and lamina, surrounding the vertebral foramen.
Regional Differences in Vertebrae
- Body of Axis: Refers to the Dens which connects with the atlas allowing head rotation.
- Transverse Foramen: Unique openings found in cervical vertebrae allowing passage of vertebral arteries.
- Superior/Inferior Articular Processes: Projections that help vertebrae connect with adjacent vertebrae and facilitate movement.
Rib Components
- Facet for Rib: The location on thoracic vertebrae where ribs articulate.
- True Ribs: The first seven pairs of ribs directly connect to the sternum.
- False Ribs: Ribs eight through ten that connect to the sternum indirectly via cartilage.
- Floating Ribs: The last two pairs of ribs that do not connect to the sternum.
Sternum Components
- Manubrium: The upper segment of the sternum.
- Body of Sternum: The central part of the sternum, where most ribs attach.
- Xiphoid Process: The cartilage tip at the lower end of the sternum.
- Sternal Angle: The joint between the manubrium and body of the sternum, indicating the level of the second rib.
Pelvic Anatomy
- Coxal Bone: Also known as the hip bone; consist of ilium, ischium, and pubis.
- Acetabulum: The socket of the hip joint where the thigh bone meets the pelvis.
- Pelvic Brim: The edge of the pelvic inlet, which separates the true pelvis from the false pelvis.
- Pubic Symphysis: The joint where the left and right pubic bones meet.
Sex Differences in Pelvis
- Male Pelvis: Generally narrower with a more heart-shaped pelvic inlet.
- Female Pelvis: Wider with a rounder pelvic inlet, adapted for childbirth.
Curvature of the Spinal Column
- Concave Curvature - Cervical: Inward curvature of the cervical spine.
- Convex Curvature - Thoracic: Outward curvature of the thoracic spine.
